Title: Improvements in and relating to tank systems
IPC: B63B11/04
Filed: 1980-07-09
Abstract: A multi-purpose cargo-tank system comprises the combination of a rigid smooth-walled tank and a collapsible tank which fits into the rigid tank. The rigid tank has a large access hatch which permits the loading of cargo pallets into the rigid tank, and the collapsible tank is provided with a rigid top member which is so constructed as to serve as the cover of the rigid tank. The collapsible tank includes a rigid bottom member, flexible membrane walls attached to the top and bottom members, respectively, and means for lowering to an operative position (as shown) and raising to a stowed position the bottom member. The collapsible tank is suitable for wet cargoes only, while the rigid tank is suitable for wet or dry cargoes. The top member of the collapsible tank has a gas-tight access port. A method of operating the multi- purpose cargo-tank system includes the step of applying a vacuum pump to the gas-tight access port of the collapsible tank when it is to be hoisted. The reduction of air or gas pressure within the tank pulls the flexible membrane walls inwards and facilitates folding of the walls as the bottom member is lifted. The method avoids the danger of the membrane being trapped and ruptured by the bottom member. The method is applicable to multi-purpose cargo- tank systems with internal dividing membranes. <IMAGE>

Title: Alarm system
IPC: G08B26/00
Filed: 1981-03-18
Abstract: An alarm system comprises a plurality of remote units connected by a common single communication cable, e.g. a domestic mains supply conductor, to receive coded address signals from a control unit and to transmit coded replying and alarm signals to the control unit. A first train of pulses, significant by number, is transmitted by the control unit to address and SET or UNSET a remote unit. Each address if successfully received causes a reply train to be generated identifying the remote unit and whether it is SET or UNSET; the control unit counts the pulses of the train and lights an appropriate indicator so that successful operation can be verified. Each remote unit also has a sensing head, responsive to intruders/smoke or whatever protection is required against, which transmits an alarm signal comprising another train of a different number of pulses, indicative of the remote unit, which the control unit counts to recognise an alarm condition and indicates which remote unit is the source while sounding an alarm.

Patent GB-2101762-A (GB)
Title: Optic fibre
Inventor: MANSFIELD ROBERT JAMES
IPC: G02B6/10
Filed: 1981-07-07
Abstract: An optical fibre such as might be used for the transmission of data or as a sensor, is formed of substantially torsion-free material which is twisted during drawing to have a rate of twist per unit length greater than the intrinsic birefringence. The material is torsion-free hence avoiding the torsional stresses which produce circular birefringence but the spinning averages out the stress induced linear birefringence and the form birefringence. The spinning thus ensures that residual polarisation mode dispersion is reduced to a negligible value. Figure 1 illustrates one technique for making such fibres, a preform (10) fed into a drawing furnace (13) is spun by a motor (11) to impart the required twist to the fibre (15).

Title: Slide rail assembly for a work vehicle
IPC: E02F3/80
Filed: 1981-02-26
Abstract: A slide rail assembly (18) and slide plate (20) are used, for example, to position an implement (14) of a work vehicle (10), such as a bulldozer (14), at various angles. The bulldozer connected slide plate (20) moves along a vehicle connected rail (22) of the rail assembly (18) to a desired position of the bulldozer (14). A pin (50) is positioned through openings (48, 52) in the rail (22) and slide plate (20) to maintain the position. The pin (50) or rail (22) can sometimes fail owing to working loads exerted on the bulldozer (14). Support members (54) each having pin receiving openings (56) in register with respective rail openings (48) are connected to the rail assembly (18) to increase bearing support area of the pin (50) and to strengthen the rail assembly (18). The support members (54) also each have openings (58) aligned with openings (44, 46) in the rail assembly (18) for relief of material packed into the rail (22) and into the pin receiving openings (48, 56).

Title: Moulding bricks of dry ice
Inventor: UMINO NAOTAKE
IPC: C01B32/55
Filed: 1981-12-11
Abstract: Liquid CO2 from cylinder 21 is blown by nozzles 13 to form dry ice snow 14 in a charging mould. A block 15 pre-compressed by piston 8 is transferred to a pressing mould when shutter 6 is fully retracted. With shutter 6 in the closed position shown, piston 10 compresses block 15 to a brick 16. Upon partial withdrawal of the shutter brick 16 is lifted into the space below the auxiliary shutter 7, the latter keeping the charging mould closed. The brick is then pushed out onto a rack 29 by the advance of the shutter 6 and a new block 15 is pre-compressed to start the next cycle. Hydraulic actuators 9, 11 and 25 are preferably heat-insulated from pistons 8, 10 and shutter 6. Shutter 6 is made of porous sintered metal to allow CO2 gas to escape into discharge passages 30. This material can also be used for the lower part of the charging mould. The pressing mould has external strengthening fins 24 which also serve to absorb heat and reduce sticking of the brick 16. <IMAGE>
